Spinal Anesthesia With Use of an Erector Spinae Plane Block Is Associated With Reduced Opioid Use and Improved Clinical Outcomes in Single-Level Transforaminal Lumbar Interbody Fusions: Evolution of Techniques and a Single-Surgeon Retrospective Analysis.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundGeneral anesthesia (GA) has long been the preferred modality of anesthesia for spine surgery, including transforaminal lumbar interbody fusions (TLIFs). However, recent advances in regional anesthesia, including spinal (awake) anesthesia and regional blocks, have demonstrated potential improvements in both surgical outputs and recovery times compared with GA. This study aims to describe the associations between regional anesthesia, clinical outcomes, and opioid utilization among patients undergoing TLIF.
methodsThe electronic medical records of a single fellowship-trained spine surgeon were analyzed retrospectively, and patients undergoing a single-level TLIF between 2018 and 2024 were included. Pre- and postoperative clinical measures (eg, length of stay, operating time, and readmission rates) and both intra- and postoperative opioid use were collected. All data were analyzed using a multivariable regression model.
resultsCompared with GA, awake anesthesia was associated with reduced intraoperative opioid utilization (
conclusionsAwake TLIF surgery under spinal anesthesia and the use of an ESP block were independently associated with reduced opioid usage, while the combined use of these techniques was associated with decreased length of stay and reduced postoperative opioid usage. Additional investigation and prospective studies are needed to further elucidate these complex relationships. CLINICAL RELEVANCE: The relationship between regional anesthesia and patient outcomes has not been comprehensively characterized in the TLIF patient population despite the growing utilization of these techniques in spine surgery. Once established, these findings have potential implications for the integration of regional anesthesia into TLIF procedures as a new standard of care. LEVEL OF EVIDENCE: Preliminary evidence suggests that regional anesthesia offers multiple benefits over GA, including health and mortality outcomes, time to ambulation and recovery, and incidence of postoperative complications. However, little is known about the applicability of these findings to patients undergoing TLIF.
